PHOTOGRAPHIC-PRINTING FRAME.

Specification of Letters Patent.

Patented Aug. 11, 1914.

Application filed February 18, 1913. Serial No. 749,225.

To all whom it may concern Be'it known that I, LAYARD L. CAMPBELL, a citizen of the United States, residing at New Brighton in the county of Richmond, State of New York, have invented certain new and useful Improvements in Photographic- Printing Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to photo raphic printing frames or holders for printing photographs and the like.

Particular objects of the invention reside in the provision of an improved frame or holder including a back board and a cover plate of glass hinged thereto and normally held spaced therefrom but adapted to be held toward the back board when the negative and sensitized paper are secured to the back board.

The invention further resides in the provision of novel lockin means adapted to be carried by the back board or fitted to an ordinary printing frame to hold the sensitized paper and negative in different relative positions in a convenient and positive manner and also to permit the same to be readily removed, thus providing for greater ease, rapidity and accuracy in printing, owing to the fact that the work is always face up.

With the above and other objects in view,

the invention resides more particularly in the peculiar combinations and arrangements of parts which will be partly illustrated as a preferred embodiment in the accompanying drawings and described in the specification, although the invention is protected for all desirable changes and uses within the scope of the invention as claimed.

Figure 1 is an edge elevation of the improved photographic printing frame with the glass plate in solid lines in an elevated position and in dotted lines in a lowered or operative position. Fig. 2 is a top plan view with the gripping elements indicated in dotted lines. Fig. 3 is a cross sectional view taken on the line 3-3 of Fig. 2. Fig. 4 is a detailed sectional view showing one of the gripping members.

The improved printing frame is shown as embodying in its preferred construction, a back board 10 of rectangular form, the same having secured, to its longitudinal edges near one end a pair of spring plates 11 which have their extremities 12 projecting rearwardly of the board. These portions 12 are twisted whereby their rear extremities are horizontally disposed and adapted to lie within the area of the longitudinal edges of the back board, the extreme ends of the plates being formed with circular bearing portions 13 which are bent upwardly. The plates 12 form springs which serve for the attachment of a glass cover plate 14 forming the face of the frame, although it is understood that this plate may be of any transparent material. At the corners of the plate 14 corresponding to the corners of the back board to which the plates 11 are secured, are attached spaced clamping plates 15 between which the glass is secured or glued, these plates 15 forming holders. The free edges of the clamping plates 15 carry a pivot 16 around which the portions 13 are enga ed but extending through recesses 17 in the rec edges of the clamping plates spaced from their longitudinal edges and by this attachment the cover plate is held normally in raised position but adapted to be moved toward the back plate and held by a spring catch 18. This spring catch is secured to the free edge of the back board centrally of its short axis.

In order to hold the negative and sensitized paper to the back board, grippin devices are provided. The gripping evice for the sensitized paper embodies a plurality of spring clips 19 consisting of sections of spring metal secured to the bottom face of the back board, the same having downwardly inclined and offset portions 20 spaced from the bottom face of the back board and then passed vertically through slots in the same as shown at 21 while their upper ends are, bent parallel to the face of the board as shown at 22 whereby the resiliency of the strips forming the grips or clips proper will permit them to move through the slots to move the portions 22 toward and away from the face of the board. These grips 19 are arranged transversely of the board but their portions 22 are arranged longitudinally to hold the upper edge of the paper therebeneath. The free edge of the paper is held beneath a clamp 23, the gripping portion 24 of which is arranged transversely of the board by twisting the metal forming the same at right angles. An operating member is provided for simultaneously moving the clips 0r grips 22 and 24 toward and away from the face of the back board, the same consisting of a flat rod or bar 25 having a depending or an angular gripping; portion at one extremity and a plurality of alternate depressions or projec tions 27 and 2-8 respectively arranged in successive relation at spaced points along the bar. Thus by shifting the bar longitudinally between the depressed portions 20 of the grips or clips and the bottom face of the back board, the depressions 27 will be brought into alinenlent with the grips and the latter due to their normal tendency to move upward will space the portions from the face of the back board, this being the inoperative position whereby the papemay be engaged there-beneath. The paper is then gripped by shifting the bar to bring the projections to alinment with the grips and thus by exerting downward pressure thereon, draw the angular portions 22 toward the face of the board and in binding contact with the paper. It will thus be seen that the grips 19 will engage the top edge of the paper and the grip 23 will engage one end thereof to positively hold sensitized paper against movement. The negative is held in position over the sensitized paper by means of grips 29 which are constructed in a similar manner as the grips 19 but which are located near the top edge of the board and to one side of the grips 19 toward the grip 23 so that when the negative is placed therebeneath it may be held or freed by shifting the grips 29 through the instrumentality of a bar 30 provided with similar depressions and projections as the bar 25 is provided with, with the exception of those for operating the grip 23. The bar 30 is also provided with a similar gripping por tion 26 whereby it may be shifted and it will be observed that the bars through the instrumcntality of the alternate depressions and projections 27 and 28 are formed with substantially cam-like faces to cause the positive application of the grips.

In the operation of the. device, the sensitized paper is first locked in position beneath the grips 19 and 23, faceside up, after which the negative and mask if desired, is locked in any position or angle relative to the sensitized paper by the grips '29. The

v lass cover plate 14: is then moved on its pivot against the action of the springs 12 and held beneath the Spring catch 18. The paper and negative are thus held from dis placement and exposure is then made. The advantage of this structure is that the printing may be done with greater ease, rapidity and accuracy as the work is always face upward and can be easily arranged and looked in any desired position.

I claim 1. A photographic printing frame embodying a back member, spring plates secured to the longitudinal edges of the back near one end and projecting beyond the same, said projecting portions being twisted substantially at right angles and having coiled extremities, a pivot engaged therein, spaced glass holding plates carried by the pivot and having recesses receiving said coiled portions, a glass cover plate held be tween said spaced plates and means for holding said cover plate toward the back member.

2. A photographic printing frame embodying a back member, spring plates secured to the longitudinal edges of the back near one end and projecting beyond the same, said projecting portions being twisted substantially at right angles and having coiled extremities, a pivot engaged therein, spaced glass holding plates carried by the pivot and having recesses receiving said coiled portions, a glass cover plate held be tween said spaced plates and means for holding said cover plate toward the back member, said cover plate being held normally spaced from the back member by the spring plates.

3. A photographic printing frame embodying a back member, spring plates secured to the longitudinal edges of the back near one end and projecting beyond the same, said projecting portions being twisted substantially at right angles and having coiled extremities, a pivot engaged therein, spaced glass holding plates carried by the pivot and having recesses rece' ing said coiled portions, a glass cover plate held between said spaced plates, means for holding said cover plate toward the back member and gripping members carried by the back member.

4. The combination with a back member and a transparent cover plate for the same; of gripping members carried by the back member, said gripping members embodying angular clips anchored to the back member and movable through the same, said clips having gripping portions overlying the face of the back member and means for moving said gripping portions toward and away from the face of the back member.

5. The combination with aback member and a transparent cover plate for the same; of gripping members carried by the back member, said gripping members embodying angular clips anchored to the back member and movable through the same, said clips having gripping portions overlying the face of the back member, said clips having portions spaced from the back member and bars engaged between said portions and the back member, said bars having cam-like faces to alternately engage between the clips and the back member whereby the gripping portions are similarly moved toward or spaced from the face of the back member.

6. The combination with a back member between the clips and the back member whereby the gripping portions are similarly moved toward or spaced from the face of the back member.

In testimony whereof, I afiix my signature, in the presence of two witnesses.
